使用Pandas保存txt文件

Question

I used pandas to replace the blank column spaces with nan in a txt file named A_B_1. How can I save this txt file as it is (blank spaces replaced with nan) to some path using pandas? I used the following code to read from it:

import pandas as pd
data= pd.read_table("/Users/Hrihaan/Desktop/Code/A_B_1.txt", sep="\s+", header=None).values

Answer 1

假设data是2D numpy数组，您首先将其转换为pandas数据框，然后使用df.to_csv并传递一个制表符分隔符：

pd.DataFrame(data).to_csv('out.csv', sep='\t')
